All releases of SHTns

Release Notes: This release adds several new features,
including support for Intel Xeon Phi (in
native mode only,
icc 14+ required).
The building process is also more robust,
and
a feature for
saving/restoring configurations allows faster initialization and better bit-level reproducibility
of results.
A few minor bugs are also fixed.

Release Notes: This update corrects a performance problem for the analysis step of large transforms, when spatial data was stored with a contiguous longitude coordinate.
Performance of this case is now comparable to other cases (e.g., synthesis and contiguous theta storage).

Release Notes: The main new feature in this release is the introduction of scalar spherical harmonic transforms of complex valued spatial data. There is also a new function for controlling the amount of informative output (verbosity). Support for Intel MKL has been improved, the header file is now compatible with std::complex (c++), and a new Python example for solving shallow water equations has been added.

Release Notes: This release fixes problems with compilation,
adds optional support for the fft provided by intel MKL,
and allows multi-threaded and single-threaded libraries to be installed side-by-side.
The multi-threaded fftw is detected more reliably.
The timing program now works on MacOS X and requires less memory.
There are also other minor fixes and improvements.

Release Notes: This release adds new functions to access more data structures (m, gauss nodes, etc.) and allows some special operators to be applied in spectral space without performing a transform (like multiplication by cos(theta)). There are also minor improvements and two important bugfixes (one specific to openmp, the other to clang).

Release Notes: This release fixes an imported bug which led to wrong results when computing gradients (functions SHtor_to_spat and SHsph_to_spat) with on-the-fly transforms. Other transform functions have been not affected, and only the on-the-fly algorithm was wrong for mmax > 0. All users should upgrade.

Release Notes: In this release parallel transforms are slightly faster and the Python interface has keyword argument support and proper exception handling. A few bugs have been fixed, and a new configure script was implemented to help with compilation and installation.
